this team could be a hell of an offensive team with the right coach. Not elite, because we don't have an elite shot creator, but definitely top 10 in the league.
Just running P&R with Lowry and AB, with pietrus and demar in the corner and Davis under the basket to grab rebounds could get you a ton of points. Virtually any good offensive system could work with the players with have.

Too bad we have no system whatsoever, our offense feels like a jam session, everybody is improvising nearly all the time and that's probably why we have these monster quarters mixed with horrible ones in the same game ...

Yeah, maybe if they weren't playing against other NBA players, they would be awesome offensively.
